The rule of adding barbell pieces is that the inner side (added first) is heavier than the outer side (added later), that is, the heavy ones are added on the inner side and the light ones are added on the outer side. Because the weight of the clip is 2.5 kg, it is necessary to add small barbell pieces below 2 kg (including 2 kg) outside the clip, and each side of such small barbell pieces is limited to 1 piece.

Most barbells in gymnasiums belong to standard barbells, but there are strict requirements for standard barbells in China. A standard barbell consists of a barbell bar (bar), a barbell piece and a clip.
